Abstract
A kind of anti-digest carbohydrate of the present invention and its processing method and application, belong to healthy food processing technique field.It is using xanthan gum and starch sugar as raw material, by acid adding and heat treatment, to obtain a kind of novel water-soluble dietary fiber containing glucose and mannosyl units.The molecular weight of product of the present invention is 600-5000 Da, the content of dietary fiber is 30%-95%, preparation-obtained dietary fiber has the characteristics that highly dissoluble, low viscosity, natural sweet taste, can be used in food and beverage, such as candy, bakery, nutritious drink, flavouring, dairy products.For the anti-digest carbohydrate of gained of the invention by xanthan gum and corn syrup mixture preparation gained, reaction condition therefore is a kind of product that mouthfeel is more preferably more natural as resistant dextrin and glucan processing conditions are mild than other.
Description
Technical field
The present invention relates to a kind of anti-digest carbohydrate and its processing method and applications, belong to healthy food processing technology
Field.
Background technique
Due to traditional living habit and food processing mode, lack many reasons such as physical training and environmental pollution,
All there is new change in national Nutritional Status and disease disease spectrum.Substantial amounts and the swift and violent cardiovascular disease of development,
" sub-health state " that the various eutrophy such as cancer, obesity, diabetes, hypertension are sick and modern society is generally existing, sternly
Important place threatens the life and health, quality of life and happy family life of people.The food development course of western developed country shows this
The origin cause of formation of a little diseases and unhealthy condition is life style and dietary structure, continues to use previous medicine thinking and treatment means i.e.
" scalpel dosing " has been difficult to solve.Nutrition-balanced healthy food is paid more and more attention, and the market of nutritious and healthy food needs
It finds out existing great-jump-forward to increase, especially carbohydrate functional food rapidly develops.
Anti- digest carbohydrate belongs to one of water-soluble dietary fiber, have low viscosity, low energy, low sugariness with
And good acid heat stability, while it will not be digested absorption in stomach and small intestine in vivo, big intestinal fermentation can only be directly entered
Using and generate short chain fatty acids, can promote intestinal beneficial lactic acid bacteria and increase, prevent colon cancer, controlling weight etc..Currently, international
The dietary cellulosic daily intaking amount that linked groups are recommended are as follows: cancer society, U.S. proposed standard is everyone 30-40g/ days, and Europe is altogether
Androgynous Food Science committee proposed standard is everyone 30g/ days.Currently, the preparation method of anti-digest carbohydrate first is that
Starch pyrodextrin under strong acid high-temperature catalytic reacts, is refining to obtain resistant dextrin, the disadvantages of the method are as follows by-product is more, purification
Difficulty, product bitter taste is big, production efficiency is low, at high cost.
The produced anti-digest carbohydrate water-soluble dietary fiber of the present invention has anti-digestion, does not increase blood glucose, proliferation
The physiological functions such as Bifidobacterium Bifidum, blood pressure lowering.In addition, containing a large amount of mannoses and poly- mannose in this product.Mannose is current
The saccharic nutrient uniquely clinically applied can be directly utilized synthesis glycoprotein in vivo, participate in immunological regulation.
For these reasons, the present invention to a kind of anti-processing method for digesting water-soluble dietary fiber carbohydrate and answers
With being studied in detail.
Summary of the invention
The purpose of the present invention is to provide a kind of anti-digest carbohydrate and its processing method and applications, are a kind of exploitations
Novel carbohydrate processing technology with excellent health value.This method has simple process, strong operability, safety
Height, advantage of lower cost, cleaning green energy conservation, can industrialized production the features such as.Obtained product has anti-digestion, does not increase
The physiological functions such as blood glucose, proliferation Bifidobacterium Bifidum, blood pressure lowering.In addition, containing a large amount of mannoses and poly- mannose in this product.Sweet dew
Sugar is the currently the only saccharic nutrient clinically applied, and can be directly utilized synthesis glycoprotein in vivo, participates in immune adjust
Section.
Technical solution of the present invention, a kind of anti-digest carbohydrate, by D-Glucose and α-D-MANNOSE sugar unit
Composition, molecular weight 600-5000Da, wherein the mass content of dietary fiber is 30%-95%.
Its molecular weight is 800-3000Da, and the mass content of the dietary fiber is 60%-95%.
A kind of processing method of anti-digest carbohydrate, step are as follows: take xanthan gum and starch sugar to hydrolyze in acid respectively,
Then the product mixing after the two being hydrolyzed, after post-processing to mixture, obtains the anti-digest carbohydrate of product；Specifically
Steps are as follows:
(1) xanthan gum sour water solution: taking xanthan gum to hydrolyze in acid, adjust to xanthan gum hydrating solution pH 1.3-2.0 it
Between, hydrolysis temperature is to 60-150 DEG C, until hydrolysate molecular mass is less than 5000Da, viscosity is less than 50 cps；
(2) starch sugar sour water solution: taking DE value is the starch sugar of 20-60, and acid is added and adjusts its pH to 1.3-2.0, is heated to
80-150 DEG C, agitating and heating 10min-48h, the compound that molecular weight is 600-5000 is obtained, substrate mass concentration is higher than
60%；
(3) it mixes: by hydrolysate obtained by step (1) and step (2) obtained material according to mass percent 0.1%-50%:
99.9%-50% is mixed evenly, and obtains the mixture that soluble dietary fibre content is 30% or more；
(4) post-process: to mixture obtained by step (3) by decoloration, filtering, ion exchange, isolate and purify, vacuum it is dense
